1. Multiple audio input interfaces, with VOD as the priority interface (with Bluetooth, USB).

2. Specially designed 5.1 channel decoding output interface, with independent volume control, convenient for external multi-channel power amplifiers.

3. Karaoke adopts stereo dual reverberation circuit, with independent control of L/R delay DELAY.

4. Unique karaoke incentive effect function, complete overload and short-circuit speaker protection function.

5. Far infrared wireless remote control allows you to operate freely (models without remote control are not equipped with this function).

6. Both the front and rear panels are equipped with microphone input sockets, making it extremely convenient for both overall aesthetics and engineering installation.

7. Built in 32BIT digital (4 levels and 2.5 scales) tone exchange and adjustment controller. (Models without modulation do not come with this feature)

8. The overall design is based on the commercial use requirements of karaoke rooms, and its volume, tone, and effects are adjusted in a hidden manner to ensure reliable operation

Specially designed two karaoke effects, karaoke stereo and karaoke mixed stereo, to enhance the surround feeling of karaoke space (these two effects can be adjusted to various karaoke sound effects with L/R: DELAY/REPEAT adjustment)
